Diesel Power Review

KHD Deutz (continued from page 21)

As far as safe starting is con- cerned, Deutz benefitted from the existence of an optional starting system on the 816 using com- pressed air piped direct to the cyl- inders. This avoids the need to flameproof starter motors and avoids the risk of sparks from gear teeth. There is the added advan- tage that an inert gas such as ni- trogen, which is commonly found in pressure cylinders on oil rigs, will perform the starting functions.

Deutz is offering a 24-page full- color brochure on its series B/AM 816 diesel engines. The brochure includes color photographs, cuta- way and sectional drawings of the engines which are offered in both in-line and "V" configurations.

Deutz maintains sales and serv- ice offices worldwide. The com- pany is represented in the United

States by Deutz Corporation of At- lanta, Ga., and Metairie, La.

KRUPP MaK DIESEL, INC.

Write 55 on Reader Service Card

Krupp MaK Diesel, Inc., a lead- ing supplier of medium-speed, four stroke, heavy-oil engines, has re- located its North American head- quarters from Rosemont to Glen- view, 111., to provide the latest state-of-the-art services to the U.S. and Canadian marine industries.

The firm maintains 112 service centers worldwide and has sold more than 700 heavy fuel engines worldwide.

Since it was established in the fall of 1980, Krupp MaK Diesel,

Inc., a subsidiary of Krupp MaK

Maschinenbau GmbH, Kiel, West

Germany, has placed more than 160 engines in operation through- out North America. "Our heavy-oil technology has been developed over the past 15 years," explains MaK vice presi- dent, Rainer Von Minden. "And new designs continue to lead im- proved operation of MaK's four- stroke engines, especially when running on bunker fuels. The ca- pability to burn heavy oil contrib- utes considerably to the reduction of operating costs because of lower fuel costs and lower specific consumption. "Although medium-speed, heavy- fuel engines are relatively new to

North America, they have proven to be very successful. . . . Our need to expand after two years in busi- ness here suggests that MaK's en- gines have been accepted by the market and become a fixture in this continent's marine industry,"

Mr. Von Minden stated.

MaK manufactures (in West

Germany) five series of medium- speed, four-stroke diesels with out- puts from 1,000 hp-13,000 hp. The engine range includes the M 282/

M332, M 453, M35, M 551/M 552, and M 601. In-line engines are produced for the entire range, and

V engines with 12 or 16-cylinders are available for very compact drive systems. All of MaK's en- gines have cast-iron crankcase housings. Engines with bores of 320 MM or more have multisec- tional engine blocks and are con- nected by continuous steel tension rods. High initial tension of the rods prevents tensile stress in the cast material. Engines with a 240- mm bore have a crankcase with an underslung crankshaft.

The M 552, widely used to power

Great Lakes Ships, has an output from 4,000 hp-10,000 hp. The three-part arrangement consists of bedplate with embedded crank- shaft, superimposed box frame with large power unit ports, and cylin- der block. The pistons are designed to accommodate the heavy-oil op- eration, including a steel upper section, aluminum piston skirt, chromium-plated piston rings, and exhaust valves in separate cast steel housings with intensive valve seat cooling. The cylinder liners are a salt bath nitrided working surface and separate cylinder lubrication.

Low engine speed and low load values combined with solid design have enabled the M 552 to run on bunker fuel of 700 CST/50 degrees

C. The M 552 is available in 6, 8, 9, or 12-cylinders. It has a 450-mm bore; 520-mm stroke, and a speed range of 425-514 rpm.

The M 601 is the largest in

MaK's series, with an output range of 8,000-12,300 hp. It is used to power larger vessels or vessels with small space capacity where higher horsepower is required.

Available with 6, 8, and 9-cylin- ders, the compact M 601 has an al- most quadratic stroke bore ratio of 600 mm-580 mm and a speed range of 400—428 rpm. It is oper- ating on bunker fuel grades up to 700 CST/50 degrees C.

The M 601 is designed with proven bedplate construction with embedded crankshaft, superim- posed box frame and cylinder block.

Well suited for most types of ships and often used as a high out- put auxiliary engine, the compact

M 453 powers propulsion systems.

With the capacity to burn bunker fuels up to 700 CST, it is designed either as a direct reversible or as a undirectional engine. The M 453 is available in 6, 8, 9, 12 or 16-cyl- inder configurations. It has a 320- mm bore, 420-mm stroke, speed range of 500—600 rpm; and an out- put range of 2,200-6,530 hp. with heavy fuels with a viscosity above 180 CST/50 degrees C.

LUFKIN

Lufkin Industries, Inc., of Luf- kin, Texas, has enjoyed an envia- ble reputation throughout the ma- rine industry for many years because of the high quality and rugged design of their marine gear drives.

Lufkin states they build marine gear drives to last even under the most severe operating conditions.

To provide vessel owners with an extra margin of protection, all Luf- kin drives employ heavy, double helical gears mounted in rugged housings capable of absorbing un- expected shock loads. Clutches are mounted externally for better access and greater ease of maintenance.

The firm stated they can and have designed marine drives for any application. Since World War

II, Lufkin has supplied a standard line of marine gear drives in ver- tical, horizontal and inline ar- rangements for 500 to 8,000 hp service. The company has custom- designed gears for much larger applications and worked with build- ers from design stages to instal- lation.

Lufkin has an informative bro- chure available at no cost which completely describes their stand- ard line of marine gear drives and the availability of custom- designed units for particular applications.

M.A.N. - B&W DIESEL

Write 57 on Reader Service Card

Ten years ago, improvements in specific fuel oil consumption was one of the least important design considerations for future genera- tions of diesel engines. This situa- tion changed radically during the 1970's and today, specific fuel oil consumption, propulsion effi- ciency, and operation on heavy fuel, outweigh all other considera- tions by a wide margin.

As a result, M.A.N.-B&W is now one of the leaders in the design of efficient engines as measured by the very low fuel oil consumptions confirmed on testbed. Actual en- gine sales, in percentage of the to- tal world horsepower demand for marine propulsion and auxiliary generator units, is in excess of 42 percent, one of the largest in the world with the broadest range of low and medium-speed engines from 500 to over 56,000 hp.
